The 1938 South Carolina United States House of Representatives elections were held on November 8, 1938, to select six Representatives for two-year terms from the state of South Carolina. The primary elections were held on August 30 and the runoff elections were held two weeks later on September 13. Three incumbents were re-elected, but two incumbents were defeated in the Democratic primary. The three open seats were retained by the Democrats and the composition of the state delegation thus remained solely Democratic.
